I have a simple question: I have a PPC 6600. AudioVox has an update on their website for the PPC 6601. Can I use this update for my PPC 6600??? This update was a major update for the phone. I had a PPC 6601 and I updated my 6601 with the recommended AudioVox update and it greatly improved my phones speed especially the Bluetooth issues that I had. If this update cannot be applied to the PPC 6600 then were can I get the update from? Does this phone already have the update? Here is the address where the update is: http://www.audiovox.com/webapp/wcs/stores/ser vlet/ProdLinksCmd?type=upg&catalogId=10001&st oreId=10001&categoryId=PPC6601KIT&langId=-1&p age=&urlString=&productId=&brand=
I look forward to hearing from anyone out there on this topic...
